Title: Method for fabricating a submarine cable having a bi-metal tube core containing optical fibers
Inventor: CHU TEK-CHE
IPC: H01B11/22
Filed: 1996-04-11
Abstract: It is an object of the invention to provide an optical fiber cable having hermetically-sealed optical fibers and excellent strength characteristics without utilizing a costly welded steel tube. It is a further object of the invention to provide an optical fiber cable that is capable of efficient and fast manufacture. These and other objects are satisfied, in accordance with the invention, by an optical fiber cable employing a novel cable core, the cable core fabricated by a method comprising the steps of: a) forming an inner, longitudinally extending, substantially-closed C-section tube having a longitudinally extending seam and an interior cavity; b) introducing at least one information-carrying component into the interior cavity of the inner, longitudinally extending, substantially-closed C-section tube; c) forming an outer, longitudinally extending tube concentrically around the inner, longitudinally extending, substantially closed C-section tube in a substantially close-fitting manner; and, d) sealing the outer, longitudinally extending tube to hermetically seal the at least one information-carrying component in the interior cavity. Advantageously, the C-section tube assists in protecting the optical fibers against crush, impact and pressure, and may also enhance the tensile strength of the optical fiber cable. The use of the C-section tube also allows the optical fibers to be efficiently introduced into the interior cavity of the C-section tube during cable production. And, as the C-section tube provides the desired strength characteristics of the cable core, the outer tube may be advantageously optimized to hermetically seal the optical fibers in the cable core. Thus, the outer tube may be designed, for example, according to its sealing characteristics and manufacturability without significant regard for mechanical characteristics such as strength.

Title: Grill apparatus, especially with wood-charcoal firing
Inventor: BUTOW KLAUS-DIETER
IPC: A47J37/07
Filed: 1996-04-29
Abstract: A Grill-Unit is described, preferably for charcoal burning, with a coal duct with a vertical U cross sectional form and lateral air vents, a grease trap tray inserted into the ducts' outer walls, with tapering guide walls rising upward from the ducts' outer walls to form a cover.  The upper portion of the cover has vertical air trap walls, which form a grid conduit upon the base of which the grating is located.  The main points are, that two parallel with one another extended coal ducts (3) are arranged at the bottom of the Grill-Unit, and that both coal ducts sit in between a vertical back wall (1) and a removable front wall (20) parallel to the vertical wall.  By removing the front wall during operation of the unit, access to the inner portion of the unit is possible if desired, for example the grease trap tray (11) may be emptied, spices and sauces may be brought in, and as well the coals may be stirred about, since they are also layed out in the coal duct box-form, in a special design.

Abstract: An apparatus and method is disclosed to resect and remove tissue. The apparatus is particularly suited for operation on the prostate for treatment of Benign Prostatic Hyperplasia (BPH). The apparatus has a deflectable member (18),which may be a wire, and which conducts electrosurgical current. The deflectable member (18) protrudes from an opening (22) near the distal end (13) of a hollow tube. Tissue is cut and coagulated by the deflectable member (18) asthe apparatus is rotated. A sharp tip on the distal end (13) of the tube allows the apparatus to be inserted percutaneously. Suction and irrigation are integral to the apparatus. One advantage of the apparatus is that tissue samples can be recovered for pathological analysis. Other advantages are that operations on theprostate can be conducted with minimal blood loss, concerns about TUR syndrome are reduced, and the bladder neck and urethra can be spared. Use of this device on the prostate also can eliminate the need for a post-operative catheter and provides immediate post-operative relief.

Abstract: Root rots are serious conifer nursery diseases.  At present, seedlings are inspected visually to determine whether they show symptoms of disease.  Cylindrocarpon destructans and Cylindrocladium floridanum are two important causal agents of root rots.  A substantially more efficient and reliable method of detecting the presence of these fungi directly from infected tissue involves the use of a set of DNA primers which can be used in conjunction with the polymerase chain reaction (PCR) to create species specific probes for detecting species of each fungi.

Title: Ultrasonic sensor for on-line detection of cutting tool insert failure
Inventor: ELBESTAWI MOHAMED A
IPC: G01N29/24
Filed: 1997-10-24
Abstract: An on-line ultrasonic sensor for monitoring and sensing failure in a cutting tool insert. The preferred embodiment of the sensor includes a piezoelectric film of aluminum nitride (AIN) deposited onto a tool insert or tool insert seat with the AIN film electrically connected to a signal generator and detection circuitry. Avoltage pulse is applied to the AIN film to generate ultrasonic signal pulses in the AIN film which are transmitted through a tool insert to the vicinity of the cutting edge of the tool insert during use. Back-reflected ultrasonic signals from the edge of the tool insert induce a voltage signal in the piezoelectric film which is analysed and compared to signals characteristic of undamaged tool inserts. Temperature increases, wear and various types of tool failure can be readily detected during use of the insert with the sensor.
